Abstract
BACKGROUND The painDETECT questionnaire (PDQ) is one of the available screening tools for neuropathic pain (NeP), with a cut-off score of 13. This study aimed to investigate changes in PDQ scores in patients undergoing posterior cervical decompression surgery for degenerative cervical myelopathy (DCM). METHODS Patients with DCM undergoing cervical laminoplasty or laminectomy with posterior fusion were recruited. They were asked to complete a booklet questionnaire including PDQ and Numerical Rating Scales (NRS) for pain at baseline and one year after surgery. Patients with a preoperative PDQ score ≥13 were further investigated. RESULTS A total of 131 patients (mean age = 70.1 years; 77 male and 54 female) were analyzed. After posterior cervical decompression surgery for DCM, mean PDQ scores decreased from 8.93 to 7.28 (P = 0.008) in all patients. Of the 35 patients (27%) with preoperative PDQ scores ≥13, mean PDQ changed from 18.83 to 12.09 (P < 0.001). Comparing the NeP improved group (17 patients with postoperative PDQ scores ≤12) with the NeP residual group (18 patients with postoperative PDQ scores ≥13), the NeP improved group showed less preoperative neck pain (2.8 vs. 4.4, P = 0.043) compared to the NeP residual group. There was no difference in the postoperative satisfaction rate between the two groups. CONCLUSIONS Approximately 30% of patients exhibited preoperative PDQ scores ≥13, and about half of these patients demonstrated improvements to below to the cut-off value for NeP after posterior cervical decompression surgery. The PDQ score change was relatively associated with preoperative neck pain.

Association between Occupation and Cervical Disc Degeneration in 1211 Asymptomatic Subjects. J Clin Med 2022; 11:jcm11123301. [PMID: 35743372 PMCID: PMC9224608 DOI: 10.3390/jcm11123301] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2022] [Revised: 05/31/2022] [Accepted: 06/07/2022] [Indexed: 01/27/2023] Open
Abstract
Magnetic resonance imaging (MRI) system has frequently observed degenerative changes in the cervical discs of healthy subjects. Although there are concerns regarding the link between an individual's occupation and intervertebral disc degeneration (IDD) in the cervical spine, whether the occupation affects IDD is still not clear. This study aimed to evaluate the occupation and IDD interplay using cervical spine MRI among a cohort of healthy individuals, and to evaluate any association between the type of labor and IDD. Using MRI, we prospectively measured at every level, the anteroposterior (AP) intervertebral disc diameter and disc height, in a cohort of 1211 healthy volunteers (606 (50%) male; mean age, 49.5 years). Using a minimum of 100 male and female each from the third to eighth decades of age (20-79 years), IDD was evaluated based on the modified Pfirrmann classification system to derive a disc degeneration score (DDS). We also measured the AP diameters of disc protrusion and of the dural sac as well as the spinal cord. The overall DDS and number of disc protrusions increased with age. Among 11 occupations, there were no significant differences in AP diameter of the dural sac as well as the spinal cord. For the four labor types (heavy object handling, same position maintenance, cervical extension position, and cervical flexion position), there were no significant differences in overall DDS and number of disc protrusions, with or without work. Also, among the four labor types, there were no significant differences in the AP diameter of the dural sac as well as the spinal cord. In this cross-sectional survey of cervical spine MRI data among healthy adult volunteers, occupation and type of labor might have no effect on IDD in the cervical spine.
